When you print out a ticket, it can get quite long. This is because unwanted headers and footers are also printed.
To fix this you can disable this option in the printer settings.
In Google Chrome:
The print screen will open automatically after completing the invoice.
Click on "more settings" on the left-hand side
Disable the Headers and footers option
Set the Margins option to Minimum
In Firefox:
Microsoft Internet Explorer
Set the margins to "minimum" and disable the "headers and footers" option.
